To all whom it may concern:

Be. it known that I, Emu: LOUIS ALFRED Saw, a citizen of the Republic of France, Department 4 of the Seine, France, have invented new and useful I mproveme nts in Apparatus for Molding Chocolate or the like Containing Preserved Fruits, Almonds, or other Hard Bodies, of which the following is a specification.

: It has hitherto been necessary in molding chocolate and the like, which is to contain almonds, hazel nuts, walnuts, preserved automatic manner and to turn cally used where fn'iit'and material of a like nature, to-do the .w'ork by'hand.

Thisinvention relates to an apparatus which-is adapted to do this molding in an the product out in an exact; uniform manner in regard -.-to'tl1e material contained in each mold and the form. of the molding. I

The apparatus herein involved is specifiit is desired to mold chocolate almond bars, said bars being of a greater thickness than the thickness of: the hard bodies to be molded with the chocolate.

It is not intended to limit the use of theapparatus to any particular or specific oporation. -All that is patentable in the dis closure,

-will be claimed in this or other applications.

The object of the invention is to provide an apparatus which will do the molding referred to above in an etficicnt and automatic manner.

Other objects of the invention will appear in the detailed description of the apparatusand of the claims annexed to said description;

Figure 1 is a side view of the complete apparatus assembled. Parts of it are shown in section to more clearly disclose the operation. Fig. 2 is a sectional view of the chocolate feeding mechanism arranged above the molds and showing spring-pressed scrapers to smooth oil the chocolate in the molds after it has been fed thcretr The apparatus disclosed herein is specifically adapted for forming the chocolate almond bar which is a well-known article of,

commerce. These bars are, in general, made up in two forms, first the bar is thin, so thatthe almonds or other nuts contained therein are not embedded completely in the chococoatod with the chocolate, they project out all over one side of the bar; second, the bar is thick and of ainple dimensions for the almonds to be completely embedded therein. In the second case, when the bars are being molded, the tops of the molds can be smoothed 'ofi by scrapers, for the almonds can be contained who 1y within the chocolate. The almonds are fed to the molds before the chocolate. The scrapers cannot be used in molding the bars in the first case, for they would tear away the almonds from the chocolate. In the first case thechocolate is fed to-the n iolds' before the almonds. which will efficiently mold bars of t e kind discussed in the first case, is disclosed in my co-pending application, Serial No. 644,977. The apparatus described in this application,

as stated, is especially adapted -for moldingbars discussed'in the second case above; but it is to be understood that the invention herein disclosed is not limited to the specific use but is capable of efficient operation, wherever scrapers can be used in molding chocolate or the like. I

Referrin to the drawings, the molds c are fed upon the track I) at one end of the machine; the chain 9 driven in any suitable manner, operates to drive the molds along the tracks up to the main driving wheel f after they have been once fed thereto; the molds then pass'one after the other, along the track, from one end of the machine to the other.- The main feeder which controls the rate at whichthe 'n ol'ds pass along the tracks, is shown at f.' This wheel f is arranged to feed the molds at an even rate along the track. The molds are shown in Fig. 2 as having three hollows each in the direction of travel. There is a certain space between each hollow, and where the molds abut, one against the other, there is a double space. The wheel f is arranged with sets of teeth, three teeth to a sct,'and between each set a blank space. This space is to accommodate the double space referred to where the molds abut one another.

Referring to Fig. 1, as the wheel f rotates, the three teeth of a set corresponding to the three hollows of any mold, will operate with said hollows to drive the mold along the track and the three teeth of the following set. will engage uniforn'ily in the three hollows of the following mold, for the space between the sets of teeth accommodates the double space made by the abutting molds.

An up ara'tus after the other, they move under the almond- -feed1 ng device e and the almonds are fed to rests against the periphery of wheel a. As

- oven and uniform feed therefrom. The

. of almonds fed to each mold. The teeth of the wheel e have a peculiar shape, that is,

' wheel a is divided by walls at. right angles molds.

This is .an important feature, as will later ap ear.

8 the molds move along the track one each mold in a quantity practically equal to the %antity fed to each of the, other his measured feeding of the almonds is accomplished as follows: The feed wheel e is connected by a chain to the wheel f, so that these two wheels operate together and in a definite speed relation. The peripheral hollows in the wheel e receive almonds fronithe hopper a, and a flap valve which is hinged loosely to the hopper a' as shown,

the wheel rotates, it acts on the flap valve to force the latter against the vertically adjustable brush 6. This action stirs the almonds in the hopper a, so that there will be an brush d is mounted as shown, to cotiperate with the wheel 6 in measuring the number they are arranged in the nature of saw-teeth, only they rotate in the opposite direction to saw-teeth.- 'The teeth being arranged this way, form hollows in the wheel a which have radial surfaces adjacent to the back of the teeth, and nearly tangential surfaces adjacent the front of the teeth. The almonds are fed into these hollowsas shown, and as the wheel rotates, the brush (Z brushes the excess almonds in each hollow up the tangential surfaces into the following hollow. This operation has been. found to be most efficient in measuring the almonds by the wheel 6, for it is found .i'i'nn experience that if the apparatus is made as described, the quantity of almonds fed to each hollow of the mold will be practically the same throughouta days operation of the molding machine. The teeth of the wheel a are alsnarranged in a corresponding manner to the teeth of the fecdingwheel 1. There are three sets of teeth in the wheel e, and every third tooth is a wide one. This third tooth corresponds to the space between the sets of teeth in the wheel 1, so that as the wheels fund rotate together, the wheel f drives the molds under the wheel e, which wheel delivers measured quantities of almonds to each mold; and while the double space between two abutting molds is being fed by under the wheel a, no almonds will be fed, because the wide tooth will then be inuncdiately over the doublcspacc. If the feed to its axis the wheel will then be divided into parallel series of compartments. The almonds would then be distributed in a uniform and positive manner and could not crowd up into one end (Jl the mold.

The molds might be sub-divided into a many compartments as desired as by crosswalls and the feed wheels a similarly divided so that the feed of the almonds to each compartment would be the same.

The specific form of the feed wheel and molds can have man variations without .departing from the generic principle of the devices herein shown. An apron is indieated, to prevent the almonds which are fed by the wheel a, from leaving the hollows thereof until the feeding position is reached. The means herein disclosed for feeding the molds along the track and the almonds to the molds is identical with that disclosed in my co-pending application referred to before and it is clearly described therein.

When the molds have been fed with almonds, they are fed into the casing as shown in Fig. 1. This casing is kept at a constant temperature by means of the electric heating device 5, and the hand thermostatic regulating device 4. A fan 0 within the casing, takes the heated air from the heating device J) and forces it to the lower part of the easing, and thus maintains a constant circulation. It the temperature falls below or rises above the point at which the thermostatis set, the circuit through 5 will be closed or opened.

Within the casing is located the chocolate feeding device an and under the trackway' which extends to the casing, asshown, is a large tank This tank is mounted on a track ":1 can be convcnientl removed from the casing, when desired. The chocolate can be. supplied to the tank i before it is put into the casing. The temperature within the easing will melt the chocolate, and the tank is also provided with a stirring device mounted on a horizontal shaft, as shown. This shaft is operated from any driving means, as indicated. it also has mounted thereon an elevating device 12. This device lifts the melted chocolate to the rotating wheel 0 and from this wheel it drops into the chocolatefeedcr m. The particular way in which the chocolate is fed into the feeder m does not specifically form any part of this invention; therefore it is only diagrammatically indicated on the drawings.

The chocolate feeder m is best shown it. Fig. 2. It is located just above the track, with space enough between it and the track to pass the molds therebetween. As the molds pass under the chocolate feeder, there are two spring-pressed scrapers t and p, which bear downwardly on the molds in the manner disclosed in Fig. 2. It can be seen clearly from the drawings that, as the molds pass by the choctdate-feeder, and the chocolate is fed to each mold. the spring-pressed scraper on the right of Fig. .2 prevents any of the almonds from one mold being pushed over into the foll wing mold. 'lhespringpressed scraper 1. pivoted at. a convenient point is adapted to have its pressitre regulated by means of the screw 1' suitably mounted, as shown. Now as the chocolate which has covered the almonds leaves the chocolate-feeder, the spring-pressed scraper with just the right amount of pressure, will smooth off the material in each mold. The

action of these spring pressed plates is one to. Now as the chocolate enters when the mold advances (see Fig. 2) it does so with a certain force and if it were not for the plate p the chocolate would rush into one mold and over into the next and very likely carry some of the almonds from one mold to the one following and thus destroy the uniformity of the product. The plate 7) absolutely prevents this undesirable action. This is clearly shown in Fig. 2. This structure overcomes one of the ditlicultics hither to found in feeding chocolate to the molds at a sufiicient speed. The plate t as shown is inclined slightly to the horizontal. It

wipes the top of each mold as it leaves the chocolate feeder-and evens off the material to a horizontal plane as shown. The inclination of this plate is just enough as shown to allow the chocolate free passage from the mold leaving the feed opening to the mold just coming up to the feed but the opening between the plate t and the mold leaving is not sufiicient to allow any almonds to pass from one compartment to another. This plate t arranged as described overcomes a serious objection present in scrapers formerly used because the almonds or other hard bodies would be pushed from one mold or compartmentof a mold to another. This undesirable action is positively prevented by the structure herein described. The molds then pass along the track out of the casing, through a small opening, as indicated, and on to a shaking tab e u. The specific form of this table forms no part of the invention and one suitable form is shown clearly in the drawings. It is not thought necessary to describe the operation of this table, as it is very well known in the art. After the molds have been on the table '11. a certain length of time, the violent shaking which the material in the molds receives through the table will force the almonds .from the position indicated in Fig. 2, to mountup near the surface of the chocolate and cause the surface to bulge outwardly around each nut to just the right amount, in order that a rich and nutty appearance of the bar will result. The driving mechanism shown above the casing, as

indicated, is adapted to drive the fan 6 and a chocolate stirrer located as indicated in the feeder m.

From the structure described, it will be seen that the molds pass from one end of the machine to the other, first having almonds ted thereto by the wheel e, then having chocolate fed thereto by the feeder m, then scraped by the spring-pressed scraper t and then passed upon a shaking table to force the almonds to the fiat surface of the chocolate bar. The apparatus thus serves to mold the chocolate automatically and turn out a product not only equal to but better than can be turned out by hand for it is of. more uniform grade and appearance.

It; is to be understood that although apmoldirig chocolate bars, any form of chocolate-almond, couldbe molded within the limits of the apparatus. For instance; instead of having long bars of chocolates, squares could be formed by properly dividing the molds by transversewalls, and by corresl'iondingly dividing'the almond feeding wheel e by transverse walls. Many other shapes besides squares could be correspondingly formed with this apparatus.
